Abstract

Purpose

To investigate the long-term surgical outcomes of conventional trabeculotomy in eyes with childhood glaucoma in a Japanese population.

Methods

In this retrospective observational study, we enrolled Japanese patients with childhood glaucoma who underwent a conventional trabeculotomy at least once before age 3 years from 1986 to 2014 in our hospital.

Results

One hundred seven eyes of 64 patients (24 girls, 40 boys; mean age, 2.8 ± 5.1 months) were included. Sixty-eight (64%) eyes had primary childhood glaucoma (PCG) and 39 (36%) eyes had secondary childhood glaucoma (SCG). The average numbers of surgical operations performed to treat the two glaucoma types that resulted in significantly (p < 0.001) different surgical success rates were 1.4 ± 0.7 and 2.1 ± 0.8. Statistical analysis showed that eyes with PCG, compared with those with SCG, were successfully treated by one trabeculotomy and up to three trabeculotomies (hazard ratios 6.66 and 4.02, respectively). Age, gender, systemic complications, corneal diameter, corneal edema, and preoperative intraocular pressure did not significantly affect the surgical outcomes.

Conclusions

Most eyes with PCG are treatable with a maximum of three trabeculotomies. However, SCG usually is refractory to trabeculotomy, and a more promising surgery must be designed.
